Can you get thrown out of a conservatoire

Hi,My daughter is considering applying for a place at a conservatoire. She has A level grade C in Music and an A and B in Sociology and History. She will be taking her grade 8 this term. She is has done well to get this far and adores playing the trumpet but I know she is not of the same calibre of people you see on young musician of the year and things like that. Some time ago I met a lady who had attended a conservatoire in the 1980s and got thrown out after a year because they felt she wasn't good enough. She was clearly still upset by the experience 30 or so years later. Does this kind of thing still happen? If so, I might try to steer my daughter more towards university as I think she would be devastated if this happened to her. Anyone had any experience of this or does it not happen these days?
